Title: Apparatus and method for focusing hard x-rays
Inventor: VALI VICTOR
IPC: G03F7/20
Filed: 1992-06-15
Abstract: APPARATUS AND METHOD FOR FOCUSING HARD X-RAYS  ABSTRACT    A dislocation-free,  composite-substance crystal having a lattice constant which decreases over the length of the crystal (38)  convergently focuses beams of hard X-rays or gamma rays (11).    A  single-substance,  dislocation-free  crystal  (34) collimates diffuse beams  of  hard X-rays  or gamma  rays  and projects the collimated radiation (11') to the focusing crystal (38).    A mask (36) is interposed between the collimating crystal (34)  and  the  focusing  crystal  (38)  causing  the  collimated radiation  (11'') to carry an image of the mask  (36).   The focusing crystal (38) produces a convergent hard X-ray beam or gamma ray beam (11''') to focus a reduced image of the mask (36) upon the photosensitive layer (41) of a water (39).  An example of a dislocation-free crystal having a lattice constant which decreases over its length (38) is a dislocation-free silicon-germanium crystal (20) wherein the proportion of germanium to silicon varies over the length of the crystal.

Title: Measuring device for measuring the liquid/dry matter mixture ratio and a method of determining the liquid/dry matter mixture ratio
Inventor: PAHLMAN HEIKKI
IPC: G01D11/24
Filed: 1993-05-11
Abstract: Abstract A measuring device for measuring the liquid/dry matter mixture ratio and a method of determining the liquid/dry matter mixture ratio. The device is a thin blade-like rod (1) arranged in a process pipe (3), the device form-ing an electric field with a frequency varying within a certain range between the electrode (2) and the pro-cess and the process pipe (3), which functions as the second electrode. In the method an alternating current having  a  fixed  frequency is  conducted through the liquid/dry matter mixture, whereby the proportions of capacitive and resistive current can be determined on the basis of the phase difference of current caused by the liquid/dry matter mixture. Thereby the proportion of capacitive current describes the liquid/dry matter mixture ratio and the proportion of resistive current describes the impurities occurring in the mixture.     (Fig. 1)

Title: Complementary logic input parallel (clip) logic circuit family
Inventor: VINAL ALBERT W
IPC: H01L21/8238
Filed: 1992-01-31
Abstract: A high speed low capacitance Complementary Logic Input Parallel (CLIP) logic family includes an FET driving stage, a complementary FET inverter, and at least one gating FET. The dimensions of the gating FET are controlled relative to the dimensions of the driving stage FETs to provide a high speed logic circuit. AND and OR CLIP logic circuits may be provided. A clocked CLIP logic circuit may be provided by adding a clocking FET. A latching clocked CLIP logic circuit may also be provided by adding a latching FET. In the latching clocked CLIP logic circuit, the gate output is latched so that it does not change during the clock period regardless of changes in the logic inputs of the circuit.      The speed of the CLIP logic circuits may be further increased by including germanium in the channel of its P-channel FETs to thereby increase carrier mobility in the P-channel FETs. The N-channel FETs are free of germanium. The internal capacitance of the CLIP logic circuits is also decreased by using common diffusion regions in the integrated circuit for pairs of driving stage FETs. Common source and/or common drain diffusion regions may be used.

Filed: 1993-10-27
Abstract: A chromaticity meter measures the chromaticity of light output for each picture element selected.  Calculated from the measurement  is  corrective data on each of RGB colors, which in turn is used to calculate corrective data on each of RGB for unselected picture elements.  In this method, original  video  signals  for  each of  RGB  colors  will  be correctively modulated based on the thus obtained corrective data.  A projected image displaying apparatus is constructed such that adjustment of chromaticity as to white as well as to black from the measurement by the chromaticity meter of chromaticity throughout the entire image,  is carried out uniformly and reliably by automatic control using a micro-computer  so  as  to  determine  the  optimal  condition  for correctively modulating the original video signal.   This apparatus  further  includes  means  for  storing  the  thus obtained optimal condition in a non-volatile memory.

Title: Air conditioning and refrigeration apparatus utilizing a cryogen
Inventor: ROEHRICH ROLAND L
IPC: F25B29/00
Filed: 1993-11-26
Abstract: Methods and apparatus for controlling a condi-tioned space to a predetermined set point temperature, utilizing a supply of cryogen. Cryogen is drawn from the supply in a flow path to provide a cooling made via a heat exchanger disposed in the flow path. A vapor motor in the flow path, downstream from the heat exchanger, drives a fan which moves air between the conditioned space and the heat exchanger. Heat is applied to the cryogen downstream from the heat exchanger, after all cooling modes have been performed, to provide the desired fan horsepower, without interfering with a coating cycle. A by-pass flow path selectively directs cryogen directly to the vapor motor, by-passing the heat exchanger, to provide air circulation in the conditioned space when the temperature of the conditioned space is satisfied.

IPC: A61B18/14
Filed: 1992-12-28
Abstract: A catheter comprises a catheter body (10) having a proximal end, a distal end, and an electrode array disposed near he distal end (12). The electrode array includes a plurality of isolated electrode terminals (18). The electrode array and a common electrode (16) are connected to a high frequency power supply (32) anc9 the common electrode (16) may be located on the catheter, may be secured separately to a patient's skin, or may be formed as part of a movable guidewire. By contacting the electrode array against a target location in the patient's body, the target location may be selectively heated, with the current density being contacted at the points of contact between the electrode terminals (18) and the tissue or stenotic material. For example, by positioning the common electrode within a stenotic region and contacting a leading surface of the stenotic region with the electrode array, the stenotic material can be heated by applying a high frequency voltage between the electrode array and the common electrode. The stenotic region can thus recanalized by advancing the distal end of the catheter body through the heated stenotic material.
